Paper Abstract

The method has been proposed for computing Fresnel-type multi-focal lenses on the basis of special-type phase nonlinearity. Multi-focal lens is represented as a mathematical superposition of a thin lens and nonlinearity distorted Fresnel lens. Selection of the nonlinearity-type is reduced to the problem of the groove form determination for the phase diffraction grating with pre-set energy distribution between orders. In particular, bifocal lens and multi-focal lens have been investigated.
